Although they have a winning record, the Giants have struggled at times, particularly on the road. With 17 of their 26 games on the road in June, the Giants need to straighten out this issue immediately.

Injuries to Ryan Vogelsong and Santiago Casilla have put their pitching staff on thin ice. The starting pitching has been especially shaky on the road, with an ERA over six away from AT&T Park.

Manager Bruce Bochy continues to maintain a steady hand in guiding the team, which has been his approach as the Giants' manager. Bochy realizes the baseball season is a marathon, not a sprint, and his solid leadership has proven to be successful.

After two months of the season, let's take a look at the first trimester grades for each player on the team.

Buster Posey

Buster Posey is the reigning NL MVP and one of the Giants' team leaders. Although Posey has been solid, he has not been spectacular, save for a few occasions.

Posey is currently hitting .304 with seven home runs and 31 RBI. His OBP of .394 and OPS of .906 both lead the Giants.

Posey has been catching more games than ever, due to the relative ineffectiveness of Hector Sanchez and Guillermo Quiroz. Sanchez was slumping so badly, he was sent down to the minors.

Posey has the responsibility of handling the Giants pitching staff, and because of their struggles, Posey gets downgraded a bit here. He has also only thrown out 21 percent of runners attempting to steal.

Pablo Sandoval

Perhaps the biggest question for fans of the Kung Fu Panda is whether his batting average will exceed his ever-increasing weight.

Sandoval has been in a recent slump, and his lack of productivity has hurt the Giants offense. In his last six games, Sandoval has gone without a hit in five of those six games. He has just two hits in his last 20 at-bats.

Sandoval's overall numbers are strong. He has a batting average of .286 with eight home runs and 34 RBI. His RBI total leads the team.

Sandoval's OBP of .327 and OPS of .766 are below each of the past two seasons.

Defensively, Sandoval has been solid. He is amazingly nimble around third base, even with his weight approaching 250 pounds.

Brandon Crawford

Brandon Crawford has been one of the pleasant surprises for the Giants this year. The Giants had low expectations for Crawford offensively, but he has easily exceeded those expectations.

Crawford is only 26 years of age and developing as an offensive player. He is currently hitting .287 with five home runs and 25 RBI. Crawford's RBI total is significant, especially since he typically bats in the eighth spot in the order.

Defensively, Crawford is outstanding. He is a future Gold Glove winner, and that could even happen after this season.

Nick Noonan

Nick Noonan won the final utility job on the Giants roster. He got off to a good start but has slumped lately. Noonan typically plays second base, and with Marco Scutaro playing well, his playing time has become very sporadic.

Noonan, in 48 at-bats, is hitting .208 with three RBI. His OBP of .255 and OPS of .484 are too low. Noonan is a player that needs to be playing every day in order to be sharp.

Ryan Vogelsong

Ryan Vogelsong was having his best start of the season against the Washington Nationals on May 20, when he broke his pinky finger swinging at a pitch. He had pitched five innings, and for the first time this year, had not allowed a run.

Vogelsong has worked 46.1 innings, allowing 62 hits and 18 walks while striking out 40. He has lost four of his six decisions, with an ERA of 7.19 and WHIP of 1.727.

Vogelsong will be 36 years of age in July and pitched a career-high in innings last year. Including the postseason, Vogelsong threw 214.1 innings, over 34 innings greater than he had ever thrown in any year of his career.

Vogelsong pitched in the World Baseball Classic, which required him to get ready about a month ahead of the other Giants pitchers.

Coupled with the fact that the Giants played until late October in the World Series, Vogelsong did not have the customary downtime that other pitchers enjoyed.

One has to question if this had any effect on Vogelsong's poor start to the season. Vogelsong stresses that his mechanics were off and it had nothing to do with the workload, but still one has to wonder.

Vogelsong is a true grinder and will work extremely hard to get back in the groove when he returns. Expect him back in late June or early July.

Although he is downgraded now, he will have every chance to turn his season around when he returns.

Chad Gaudin

Chad Gaudin is a 30-year-old journeyman pitcher. In his career, he has pitched for nine different organizations in the big leagues.

He came to the Giants this spring as a non-roster invitee and threw the ball extremely well. The Giants were looking for a long reliever that could give them as many as three innings in an outing. Gaudin has done a tremendous job for the Giants.

In 30.2 innings of work, Gaudin has allowed 24 hits and walked 14 while striking out 28. He has an ERA of 2.05 and WHIP of 1.239.

Gaudin may get his first start of the season against St. Louis on Sunday.

There's Plenty of Baseball Left

The San Francisco Giants have lost 10 of their last 15 games and five of their last seven. The starting pitching has been the main culprit, as the Giants pitchers are not getting deep into games. This taxes the bullpen, and the overworked relief corps has started to fade.

With very few grades at the A or A- level, the fact that the Giants are only two-and-a-half games out of first place in the NL West gives them a lot of reason for optimism.

Offensively, the Giants lead the league in batting average and are fourth in total runs scored. This is a major shift from the team that has always relied on its pitching to win games. Now, it is the pitching that has been letting the Giants down.

Injuries to Ryan Vogelsong and Santiago Casilla put more pressure on the Giants pitching staff. With a very tough month of June on the horizon, the Giants have to hold their own as they wait to get healthy.

The good news is nobody is running away with the NL West, so look for the Giants to be in the playoff hunt over the course of the season.

If the pitching improves, the Giants will have the inside track at a playoff berth as they try to defend their World Series title.
